Description
Standard blades compromise efficiency in severe environments. The Nakamura Impact Series is specifically engineered for extreme working conditions. Whether processing materials with heavy adhesive layers, dense hardwood knots, or embedded metal fasteners, our Heavy-Duty Impact design minimizes equipment downtime. By prioritizing high-impact tooth retention, we ensure sustained cutting stability.
- Better suited for knotty lumber, reclaimed wood, and glue-layered boards;
- Focuses more on tip retention and cutting stability under impact load;
- Rugged TCT design is better suited for contractor use and heavy-duty jobsite cutting;
- Available in different diameters, bores, and tooth counts for multiple machine setups.

DETAILS
- Heavy glue layers and dense knots generate excessive friction and thermal stress. The Impact Series features a specialized Rugged TCT geometry optimized for rapid chip evacuation. This minimizes heat accumulation and prolongs blade life in abrasive applications.
- Demolition and material recovery applications cause premature wear on standard teeth. We utilize advanced brazing processes and high-impact carbide grades to process Nail-Embedded Wood efficiently, significantly reducing the risk of tooth fracture.

Application

Instructions
- Protect the Edge Coating
These blades come with a factory-applied anti-rust coating. If the blade isn't in immediate use, avoid touching the carbide tips with bare hands. Store it in a dry environment to prevent the exposed carbide from oxidizing, which directly degrades initial cutting performance.
- Handle with Care Off the Saw
While the Impact Series is built to smash through hidden nails, the steel body is precisely tensioned. Dropping the blade on a concrete floor can alter the plate's tension and cause runout (wobble), which ruins cut quality and reduces blade life.
- Know When to Replace
Pushing a severely dulled blade through hardened glue or knots generates excessive heat. This risks catastrophic blade failure and operator injury. Swapping out dull blades promptly is the best way to maintain safety and keep your actual cost-per-cut low.
